Over A Torrent Sea, by Christopher L. Bennett
This story is one of the multitudinous episodes in book form in the Star Trek canon, and this particular one is an adventure of the Star Ship Titan; although I wasn’t familiar with this ship, or the events which precede this story, the fact that I know the captain, William Riker, from the Star Trek: The Next Generation television series, means that I felt comfortable reading it, without a steep learning curve required to acquaint myself with a lot of new characters [although there are quite a few]. I’ve never been able to understand how the Stardate system works, but at the beginning of the story, we are given an equivalence between Stardate 58126.3 & 2381 in the current western system: no doubt I could look it up online, if I could be bothered….. There must have been a series of books preceding this one, entitled Star Trek: Destiny, detailing “devastating events”, according to the book’s cover, presumably involving The Federation’s arch-enemies, the Borg, who have, also presumably, been defeated, enabling “Captain William Riker and the crew of the U.S.S. Titan … to resume their deep-space assignment, reaffirming Starfleet’s core principles of peaceful exploration.”
They encounter a very unusual planet, one consisting of a global ocean, with no apparent solid land to be seen anywhere. They [as in, the English-speaking ones] name the planet Droplet and, initially, it appears that it is devoid of any life, sentient or otherwise, but luckily, there is in the crew an aquatic lifeform, Aili Lavena, who is able to explore the oceans freely [and joyfully], unencumbered by the life-support suit she is obliged to wear in gaseous atmospheres; she has also, because her species is unashamedly promiscuous at a specific period in their life-cycles, enjoyed a brief but rewarding liaison with Will Riker, which will become a matter of some embarrassment for him as the story unfolds, especially as he is now in a serious relationship with the ship’s Counsellor, the Betazoid empath Deanna Troi, who must have moved with him from Enterprise, for that very reason: she is in the late stage of pregnancy, having tragically lost a previous baby by miscarriage.
It is discovered that there are, in fact, lifeforms in the ocean, capable of living at great depths, but it isn’t clear whether they are sentient, or simply ‘animal’; because they look like an amalgam of a whale & a squid, they are called squales. The question of sentience is almost resolved when Lavena is rescued from a predator, and it is confirmed when the squales destroy probes which have been submerged to warn them away from an area which would be dangerous for them, as a result of an underwater tsunami; also, Lavena has been able to establish primitive communication with them, as her own language bears some basic similarities, so she learns that technology appears to frighten them. Inevitably, the Federation’s Prime Directive has to be considered when a rogue asteroid appears to be on course for the planet, and Riker has to decide whether they can reveal their extraterrestrial origin, something which has thus far been carefully concealed. Revealing any more would probably spoil the plot which, if you enjoy science fiction in general, and the Star Trek canon specifically, is exemplary of the Star Trek ethos; in particular, how all life, in its great diversity, is precious, and that difference in all forms should be respected, and not feared. The paperback I read should still be available, but it might necessitate some effort in locating: I like to think that effort will be rewarded.
